Thermal Injury to Normal Dog Teeth: in Vivo Measurements of Pulp Temperature Increases and Their Effect on the Pulp Tissue

Temperature rise on dentin caused by temporary crown and fixed partial denture materials: Influencing factors

“…fabrication technique, type of matrix used), 3,10,[16][17][18] as well as to the remaining thickness of the cut dentin wall. 12,15,19 In vitro test-setups have been developed for determination of the temperature occurring inside the pulp chamber to asses the potential of pulp damage. 10,12,17,18,[20][21][22][23][24][25][26] The temperatures determined range between 40 8C and 80 8C.…”

Influence of heat from light curing units and dental composite polymerization on cells in vitro

“…1,2 Dental treatment often results in a temperature increase of the tooth surface and therefore the tooth pulp. The pulpal temperature increase may be caused by rotating instrument tooth preparation, [3][4][5][6][7] ultrasonic instrumentation, 8 laser treatment, [9][10][11] electrothermal debonding of ceramic brackets, [12][13][14] light-enhanced bleaching, 15 temporary crown and bridge materials [16][17][18] or the light curing of dental composites.…”

Pulsed Nd:YAG laser irradiation of the tooth pulp in the cat: I. Effect of spot lasing

“…However, there is also a report that the exposure of nerve fibers to a high temperature environment decreased the amplitude of compound action poten- tials evoked in them in a short time [16,17]. However, the increase in the pulp temperature produced pathologic changes in the pulp tissue [18,19], even though there is still an unclarified reason why laser irradiation can decrease intrapulpal nerve activities observed as ACAP in this study. The severe pathologic changes in the pulp tissue caused by lasing may be induced mainly by thermal effects produced by irradiation with the pulsed Nd:YAG laser.…”

“…The Nd:YAG laser could easily penetrate the dental hard tissue [20] and was absorbed into the hemoglobin in the red blood cells, where the laser energy can be transferred into heat energy. However, dental hard tissues such as enamel and dentin have adiabator properties and can usually protect the pulp inside from external high-temperature thermal stimuli [18]. It is easily speculated that adiabatic dental hard tissue may accumulate the heat inside the pulp, which then produces heat-related damage in the pulp tissue.…”
